“One of the characteristics of love relationships that flower is a relatively high degree of mutual self-disclosure–a willingness to let our partner enter into the interior of our private world and a genuine interest in the private world of that partner. Couples in love tend to show more of themselves to each other than to any other person.
This implies that they have created an atmosphere of trust and acceptance, but it implies more than that. It implies first and foremost that each is willing to know and encounter him- or herself. This is the necessary precondition of the willingness for mutual self-disclosure.
